^ SA9804E Siphon Hose

If the fuel pump is inoperative, the tank can be drained by siphoning from the tank. A suitable means is through the fuel filler pipe with the "correct" type and stiffness of tubing as used with the SA9804E siphon hose assembly.

CAUTION: Do not attempt to insert any other type of siphon hose or tube into the fuel filler pipe. The design of the inlet check valve at the end of the fuel filler tube (see "fuel inlet check valve") restricts the insertion of a hose and, most importantly, prevents the removal of this hose. if the siphon hose becomes stuck in the check valve, the fuel filler pipe will not be able to be removed from the fuel tank without damage to the fill pipe or fuel tank.

1. Disconnect the negative battery cable.
2. Open fuel filler door and remove gas cap.
3. Insert siphon hose guide/funnel into fuel filler pipe.




4. Insert siphon hose (SA9804E) into guide funnel and into fuel filler pipe. Some resistance may be encountered when the tip of the siphon hose reaches the inlet check valve. Repeated probing may be necessary to slide the hose tip through the check valve cage.

IMPORTANT: The siphon hose will reach the bottom of the tank within about 10 inches of the end fitting (and tag). When connecting the siphon hose to another length of hose connected to the fuel drain tanker: DO NOT insert the siphon hose into the fill pipe funnel past the tag at the fitting end. If inserted too far, the upper portion of the siphon hose may pass through the check valve cage and then jam on attempted removal.

5. Begin the fuel siphoning process.

NOTE: The fuel flow rate from the siphon hose will range from 0.3 gal/min up to 1.0 gal/min (depending on whether it is gravity siphoned or with an air-powered pump).

6. Remove siphon hose from fuel filler pipe after draining is complete.
